0.33 Ct. Greenish Blue Sapphire from Madagascar

From the weathered alluvial beds of Madagascar to the precise hands that shaped it, this greenish blue sapphire carries a story of place and craft. Formed over eons under geological conditions unique to its island home, this gem was gently liberated from its matrix by miners who know how to read the language of the earth. At The Natural Sapphire Company we honor that beginning, and we bring this stone into focus with respect for its origin and with an eye for its future as a wearable treasure. The natural hue that whispers of ocean coves and misted lagoons is a reminder of the remote landscape where the crystal grew, and that quiet provenance is a foundation for the intimate story this sapphire will tell once set into jewelry.

Measured precisely at 0.33 carat, this round sapphire presents compact proportions that make it ideally suited for custom work, measuring 3.68 by 3.63 by 3.10 millimeters. Cut in a mixed brilliant style to balance facet brilliance with depth of color, it offers scintillation that plays across the table and crown, while its excellent polish gives each facet a crisp, clean finish. At eye level it is graded as very slightly included, which allows the gem to remain transparent and lively, while the medium intense color intensity imparts a refined greenish blue that is neither overpowering nor faint. The stone has been heat treated for color enhancement, a traditional and stable method that deepens its tone without masking the natural character derived from Madagascar.

Because of its small, round outline and balanced depth, this sapphire is particularly versatile for custom jewelry design, and it excels in settings where precision and proportion matter. It is an excellent choice for a delicate engagement ring center designed for someone who prefers subtlety, or for a perfectly scaled accent stone in a three stone piece that pairs it with larger side gems. The round, nearly symmetrical dimensions make it predictable for bezels and classic prong mounts, and its mixed brilliant cut ensures it will hold its own in halo configurations, cluster designs, and as the luminous focal point in fine pendant or stud earring settings. Jewelers at The Natural Sapphire Company often recommend round sapphires of this size for bespoke stackable bands and for intricate pavé patterns where uniformity and sparkle are essential, because the stone measures consistently and sits well against the metal in close set work.

Choosing this sapphire creates a direct connection between the wild origin of a precious material and the intimate, wearable art that follows, and The Natural Sapphire Company is here to translate that connection into a custom piece designed to last. The subtle greenish blue tone invites pairing with warm or cool metals, and its very slightly included clarity provides character that reads as natural and honest, while the excellent polish elevates every reflection. If you are imagining a personal creation that tells a layered story, this 0.33 carat round Madagascar sapphire offers a compact, luminous canvas for creativity, and our design team will work with you to select settings that honor its proportions, protect its integrity, and showcase its natural glow. Embrace a gem that began its journey in ancient rock, was refined by careful cutting, and is ready to become a new chapter in a piece of jewelry meant to be worn and treasured.
